Introduction

Here, I show the analysis of rainfall patterns for the livestock project. Firstly, I picked up 13 focal sites which had average annul precipitation = 800 mm ± 20% over the past 100 years from SA, VIC and NSW as below.

Seasonal extreme events

Then, I assessed extreme dry events in each site for winter, spring, winter & spring (W_S), May and June. The extreme events were identified as years with the driest seasonal precipitation over the past 100, 30 and 10 years.

Seasonal rain distribution. The driest year during each season is shown with red.

Seasonal rain distribution. The driest year during each season is shown with red.

Autumn break

Autumn break was defined as the first rain date between May and June that had the total of ≥30mm rainfall within the following 4 days (i.e. sum of 5 days) followed by ≥20mm rainfall within the subsequent 30 days. Percent quantiles of the autumn break date are shown in the table below for each site over the past 100, 30 and 10 years. The first day in May (1st May) is Day 1.

Summary figure

Autumn break dates are plotted against years as below.

Temporal change in the autumn break date with a regression line. The 1-5th driest years are shown with colors and otherwise with grey.

Distribution of autumn break dates. The above results are summarised in a box-whisker plot as below.

Characterisation of rainfall patters in extreme years

I characterized the rainfall pattern during extremely dry years using indices below.

Below, I summarize multi-site data and demonstrate the magnitude of extreme events given as \((x_e-x_a)/x_a\), where \(x_e\) and \(x_a\) are average values in extreme years and across all years, respectively.
